V GS(th) is the gate threshold voltage of the external pass transistor and may be obtained from its datasheet. V GS(lim) is the pass transistor gate-source voltage required to obtain the limit curent. It is dependent on the pass transistor’s characteristics and may be obtained from the transfer characteristics curves on the transistor datasheet. g fs is the transconductance of the pass transistor and may be obtained from its datasheet. R FB is the internal feedback resistor and is 5.0kΩ nominal. 1. 2. 3. 4. 5.
